Just in time for Easter, the Boston-based candy company Unreal has launched a PR offensive featuring Tom Brady. The Pats QB is among several A-list celebrities — Jillian Michaels, John Legend, and Leonardo DiCaprio are a few others — involved in the company’s so-called Easter Bunny Apology Tour. Unreal, which calls itself the “unjunked junk food company,” makes candy without corn syrup, hydrogenated oil, artificial flavors, GMOs, or synthetic colors.
